<p class="Abstract">This paper illustrates a case study related to the characterisation of corrosion products present on recently excavated artefacts. The archaeological findings, from the Rakafot 54 site (Beer-Sheva, Israel), consist of 23 coins and a pendant, all dating back to the Roman period. Raman spectroscopy was used to identify the corrosion products that compose the patina covering the objects. To facilitate and support their identification, spectra were then processed using principal components analysis. This chemometric technique allowed the identification of two main compounds, classified as atacamite and clinoatacamite, which formed the main components of the patinas. The results of this investigation can help in assessing the conservation state of artefacts and defining the correct restoration strategy.</p>

Active Corrosion

The components of corrosion products on rusted cast iron artifacts in a wet/dry atmospheric environment have been studied by micro-Raman spectroscopy. The observations show that microstructures of outer and inner interfaces are different; indicating that active corrosion occurred on the rusted specimen covered with many cracks and pores. The μRaman spectra of outer and inner layer results prove to be composed of three main iron oxyhydroxides. In addition, Fe3O4 only exists in the inner layer.
